Abstract
Compositions for treating hair prepared using fluorinated acids to neutralize polymers with basic groups are described, which contain a complex formed from at least one fluorinated acid and at least one polymer with basic groups or a complex of a salt of a fluorinated acid and a polymer with protonated or quaternized amine groups, and which also contain at least one film-forming, hair-fixing polymer. These compositions deposit a reduced amount of residue on the hair without reducing the hair-fixing performance.
